BXCYCLE GEAR.

Application led July 24, 1922.

To all whom t may concern:

Be it known that l, AUGUsTUs Linen, a citizen ol' the -United States ofAmerica, and resident of ltowe, in the State of Massachusette, UnitedStates of America, have invented certain new and useful lmproveinents inBicycle Gears, of which the following is a specification.

This invention relates to improvements in bicycle gears, and the objectsof the invention are to provide a relatively high gear 'for test ridingwithout the necessity ot employing; sprockets or gears o undulyincreased size.

l5 Further objects oi the invention are generally to improve andsimplify the construction of the gear to better adapt the various partsto perform the functions required of them.

And it consists essentially of the improved construction hereinafterdescribed in detail in the accompanying specification and drawings.

ln the drawings;

E5 lfigure l is side elevation of the gear and ci" the bicycle showingthe method oi'V attaching' the gear.

TFigure 2 is a sectional detail of the gear.L

Figure 3 is a detail in elevation of the main driving `gear.

ln the drawings, like characters oi" reference indicate corresponding`parts in all the figures.

lieiferrinp,` to the drawings; indicates the crank having the usualpedal lO thereon. ln accordance with the present invention the crank isoperatively connected to an internal gear B which turns therewith andwhich meshes with a pinion 49 C on a. counter-shatt D journalled in abearing` l2 on the Jrra-me, the opposite end of the counter-shaftcarrying a sprocket E which connected by a chain 13 with a correspondingsprocket lelwhich turns with the rear wheel F of the bracket and ispreterably ,connected to the hub 15 thereof in the usual way.

Serial No. 577,169.

rEhe sprocket E is preferably larger than the sprocket le and the gear Bis of a suitably larger size than the pinion C. lt will 50 be seen that,in this way, a very considerable multiplication oi" speed is obtainedbetween the various gears, and this is accomplished by minimum parts allwell designed to perorin the functions required o' them. 55

ln order to strengthen the trame and enable it to better support thegear, l provide a second diagonal bar 20 parallel to the rst diagonalbar :2l and provide a second hori- Zontal bar 22 parallel to the lowerhorizon- 60 tal bar 23, the bars 20 and 22 .meeting at the bearing l2which .journals the countershaft D.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention, within thescope ot' the claim, constructed without departing from the spirit orscope thereof, it is intended that all matter contained in theaccompanying specitication and drawings shall be interpreted asillustrative and not in a limiting sense.

lVhat l claim as my invention is:

,A bicycle of the character described comprising` a pair of diagonalbars spaced one above the other, a pair of similarly spaced horizontalbars connected at their inner ends to the diagonal bars to form an upperand lower frame, a counter-shaft supported in a bearing in the upperframe, a pinion and a sprocket on said shatt, a crank shaft in the lowerframe having an internal .gear adapted to engage with the pinion on thecountershaft, and chain means connecting the sprocket on thecounter-shaft with a sprocket on the driving wheel.

In Witness whereof l have hereunto set my hand in the presence ot twowitnesses.
